Application filed April 20, 1917. Serial no. 163,482.

To all whom it may concern."

Be it known that I, SELMER O. Hort, a citizen of the United'lStates, residing at Trail, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Tires, of which the following is a specification.

My invention relates to vehicle tires and more particularly to an automobile tire, the principal object being to provide a tire which will possess the resiliency thatpneumatic tires that are now to obviate the danger of punctures and other tire trouble to which these pneumatic tires are subjected.

A further object of the invention is to provide a tire for automobiles and other vehicles which consists primarily of a plurality of bowed leaf springs which will rein der the tire strong and durable and possess a maximum amount of resiliency.

Still another object is to provide a resilient tire which is easily assembled and dis assembled and the parts of which may be replaced should the original ones become Worn or broken.

It is another object to provide a resilient or spring tire possessing the above outlined features and others to be hereinafter dis cussed and which may be readily and easily attached and detached to and from the wheel.

An additional object is to provide a spring tire which consists of few easily arranged elements which are not likely to become inoperative and which may be manufactured and placed On the market at a minimum cost.

The above general objects together with others will be fully set forth in the follow ing description, illustrated in the accompanying drawings and explicitly defined in the appended claims.

n the drawings:

Figure 1 is a side elevation of a tire constructed in accordance with my invention, part of the tire being broken away.

F ig. 2 is a transverse sectional view through my improved tire, and

Fig. 3 is a longitudinal sectional view of the same.

Referring in detail to the drawing in which like characters of reference designate like parts in all the views the numeral 5 designates a ring which is formed of the usual metal and is bent to provide spaced in use have and yet parallel flanges 6 which extend clear around the peripheral edge of the ring.

The numeral 7' designates the bowed springs of my improved tire which are formed of any suitable grade of metal and which possess the desired strength and Te siliency. These springs 7 are of a uniform width and thickness and are secured to the flanges 6 ofthe ring at their extremities by means of transversely extending bolts 8 which extend therethrough and through these flanges. Removable nuts 9 are threaded on these bolts 8 and bear against the ad jacent extremities of the springs. These springs 7 are spaced apart for a relatively great distance as clearly indicated in F ig. 3. Preferably the space between these springs is approximately one inch.

Overlying the springs 7 are tread members 10 which are formed with substantially rectangular enlargements 11 at their centers and are of uniform width beyond these enlargements. These enlargements abut and are disposed at the crest of the tire as clearly indicated in Fig. 1. The extremities of the tread members 10 extend toward the flanges 6 and are secured thereto in a manner which will be set forth below.

Disposed between. the bowed springs 7 at their extremities and underlying the extremities of the tread members 10 are spacing blocks 12. Extending transversely through the extremities of these tread members 10 and the spacing blocks 12 are bolts 13 that extend through the flanges 6 of the ring 5 and have nuts 14: threaded thereon. These tread members are formed of any desired material such as canvas, leather or in fact any other material having the desired thickness and flexibility.

It will be seen that the tread members be ing in contact with one another will provide the tire with a smooth continuous tread. It will be manifest that the tire is to be used in conjunction with any conventional wheel and retained thereon by the usual fastening means that are used in connection with con ventional demountable rims.

From the above disclosure it will be seen that I have provided a tire which does not necessitate inflating and which possesses the resiliency that pneumatic tires possess and which is very durable.

This disclosure is merely illustrative and it is to be understood that the inventive idea llllt! can be carried out in' than the one herein specified and illustrated and that I will be justified inmakingesuch modifications which, may be "embodied in' the scope of the appended claims.

What is claimed is:

'1. 'A spring tire comprising a rlnghavingg extending around its pe- V annular flanges ripheral edges, bowed leaf springs secured to the flanges and arranged in spaced relation, tread members overlying the spaces between the springs, enlargements formed upon thetread members and abutting each other, spacing blocks arranged between the extremitiesofthesprings, and meanssecuring the tread members and spacing blocks to the flanges of the ring.

7 2. A tire including a ring, annular flanges extending outwardly from opposite sides Copies of this patent may be'obtained for constructions other r endsieng'aged 'with said flanges, a plurality- ,of fastening bolts passing through said .flanges and through the ends of said springs, *a pluralityof tread members supported upon said supporting springs and arranged to close the spaces therebetween, and a plurality of fastening bolts passing through saidflanges and'fastening thefends of said tread members thereto.
